Question
What is the energy of a photon of light with a frequency of 6.5 x 10^14 Hz

Answer
To determine the energy of a photon all you have to do is to multiply the frequency f of the light by Planck's Constant h since the energy of a light wave is proportional to the frequency of the wave:
E=h*f=6.63x10^34Joule*sec x 6.5x10-^14/sec=4.31x10^-19Joules
